Login screen does not show after recent update

Once again I am having issues with turning on my computer after a system update. Is there any known recent issue with NVIDIA and KDE-based Manjaro these last weeks?

I can see the computer turning on, the monitor shows the motherboard logo, but then the login screen doesn’t show. How to access the TTY1 terminals? Pressing Ctrl+Alt+1, 2, 3, … doesn’t work.

I could even see the mouse in the first attempt, but now the mouse is gone as well.

CTRL+ALT+F3 or so for TTY3. Also check your /var/log/pacman.log for clues.
